GURRENT-LIMITER.

Specification of Letters Patent.

Patented Mar. 4, 1919.

Application filed January 25, 1916. Serial No. 74,228.

To all whom it may concern:

Be it known that I, KRISTIAN Pn'rTERsnN, a subject of the King of Norway, residmg at Sarpsborg, Norway, have invented certain new and useful Improvements in Current-Limiters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this spec1fica tion.

This invention relates to improvements in current limiters and similar devices of the kind used to control the consumption of electric current in two or more places of consumption, in each of which the current consumed is paid for according to a particular rate.

This, for instance, is often the case when in a house electrical current is used partly for lighting, and partly for cooking or heating purposes. In this case the current used for lighting purposes must often be paid for at a higher rate than the current used for cooking and heating.

The object of the present invention is to provide a current controller which will be less influenced by some currents than by other currents passing through it, so as to enable the consumption at different places to be controlled by the same apparatus, the said apparatus being influenced by the different currents in a ratio corresponding to the different prices of energy at the several places.

In the accompanying dra'wingthe lamp connections are indicated at 1, and the cooking apparatus or the like by 2. There is a separate coil, 5, 6, for each of the connections 1, 2, and each coil is provided with a separate core 7, 8, for actuating adjustable armatures 9, 1O fastened by means of screw threads on a common lever 11 pivoted at 12. The said lever may be the actuating lever of a current limiter or the like, and the form of apparatus illustrated is particularly adapted for current limiters.

The lever 11 is held supported by a spring 3 and closes contacts 13 and 14 of any well known limiting device, here indicated as a solenoid 15 whose core 16 attracts an armature 17 on a lever 18 pivoted at 19. The tail of this lever connects to line through contact 20.

The influence of the currents through 1 and 2 on the apparatus may be adjusted by means of the screw armatures 9, 10 as well as by means of the cores 7 8, which may be moved longitudinally.

I claim 1. In a current limiter, a pivoted lever, a pair of adjustable armatures therein, two branch electric circuits, translating devices in each branch circuit, a winding included in each branch circuit and a core for each winding arranged opposite the respective adjustable armatures.

2. In a current limiter, a pivoted lever, a pair of armatures adjustably threaded therein, a pair of branch electric circuits, a winding in each branch, said windings havin different numbers of turns, a core for each winding opposite the respective armatures, and translating devices of different current consumption in the branches.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.

KRISTIAN PETTERSEN.
